Nowadays, agro-firms are confronted with competition from global suppliers in both domestic and export markets. Such competition in sustainable agro-operations is expected to intensify. The survival of these firms in developing countries urgently requires a significant transformation to be competitive. This paper discusses the rationale of adopting a national innovation (NI) approach from an industry-wide perspective. In order to attain sustainable agro-operations in developing countries, the approach stresses appropriate scientific and technological applications and effective linkages of technology transfer via the network between public and private institutions, universities and other research institutions. Central to this approach is the development of the agro-industrial sector whereby agri-chains are formed. An illustrated case of the NI approach is presented with respect to a small island developing state, the Republic of Trinidad and Tobago.

Previous research on two-sided markets has, for the most part, concentrated on indirect network externalities between buyers alto sellers. This paper considers direct competition effect among sellers and among buyers as well as indirect network externalities. We develop an analytic model of C2C e-marketplaces and examine whether a monopolistic incumbent could successfully deter new entry into its market. We find that the effect of the number of sellers or buyers on the price of goods depends on whether sellers have decided to sell the goods using an auction or fixed pricing rule and on the characteristics of the goods. We argue that when the effect of the number of sellers on the price of goods is significantly larger than that of buyers, there is a high possibility of entry. In particular, we show that entry becomes more difficult to deter as fixed-price format is adopted more frequently or the proportion of collectables is relatively low.

Digital convergence which means the convergence of industry areas related to digital technologies is an important phenomenon in business, which will decide the fates of firms in the near future. The only firms which can create synergy effects from digital convergence are expected to be the winners in the fierce competition of digital convergence era. In our analysis, we examine the strategy of an integrated firm which has businesses in two different industry areas which are related to each other. By using a game theoretical model, we show how the integrated firm can win over two single separated firms which have business in only one industry area each by leveraging the two businesses the integrated firm has. In our welfare analysis, we also show that this convergence may be even beneficial to consumers, which seems counter-intuitive to social concerns about anti-competitive behaviors by integrated firms. Additionally, we study comparison between industry convergence and product convergence.

Busan North port is facing crisis due to the opening of the New port. The North Port and NewPort are competing for a limited volume of cargoes and this competition is leading after all to price competition, lowering cargo work fee that may result in the failure of both This paper proposed the balanced development plans, which are the strategies of business tie-up and activation between the North Port and NewPort by introducing the strategy of "co-opetition" and the analysis for the success factor of co-opetition: to solve this operational problems on Busan port. It is found out that activation strategy is more successful co-opetition strategy than business tie-up strategy. The execution for the two co-opetition strategies will lead Busan Port to the balanced development as well as the enhanced competitiveness and will leap Busan port into global hub port as well.

Based on the fact that Qingdao port, Tianjin port and Dalian port of the economic circle around Bohai have been the three islands of stability through long-term competition, this paper conducts a system study on the competitive powers of the three ports through AHP model on the analysis of current status of the three ports, and probes deeply into the outer factors and the inner factors affecting on the competitive advantage, and points out the existing problems in competition. We think that the three ports must compete orderly and collaborate closely, and give the forms and approaches developing strategy collaboration in order to obtain an advantageous position in Northeast Asia and improve the international competitive power.

This paper is concerned with the traveling wave solutions of nonlocal dispersal models with nonlocal delays. The existence of traveling wave solutions is investigated by the upper and lower solutions, and the asymptotic behavior of traveling wave solutions is studied by the idea of contracting rectangles. To illustrate these results, a delayed competition model is considered by presenting the existence and nonexistence of traveling wave solutions, which completes and improves some known results. In particular, our conclusions can deal with the traveling wave solutions of evolutionary systems which admit large time delays reflecting intraspecific competition in population dynamics and leading to the failure of comparison principle in literature.

When studying the film industry, researchers have seldom addressed the dynamic interaction between marketing information and word of mouth in the motion picture industry mainly because of the limitation of traditional research methodologies. This study explores integration and competition among important variables influencing on audience's choice on movie selection, particularly by using a new method of agent-based modeling including competitive environment. Decision process of moviegoer composed of transition probability based on multinomial logit model, considering marketing and box-office information, critique, and word of mouth from other moviegoers. After validating the fitness of market share among released movies, this study conducted a set of simulation experiments considering several variables such as market size, change of weight between variables, and movie performance under competition. Propositions are derived from the simulation results is also suggested for future research.

The growing mobile products market is expected energy efficiency. So product design is more important focusing on reducing power consumption than improving technology of color sense. A Organic light emission diode is in limelight of the best display to satisfy market expectation. A Organic light emission diode is achieved low power consumption, pixel response which was fast for its time, high contrast of brightness and wide color reproduction raio. Therefore there is a fierce competition for the organic light emission diode development between a country and another country over business. The technical value's life is short because of a fierce development competition, and there is little probability that technical success become business success. In this study, the purpose is reduce the time for life test by accelerated current and it can do production possible design by accelerated life model in design phase.

We consider the product differentiation model of online channel competition and examine the strategies of hybrid firms in terms of efficiency. After measuring the social cost of online business strategies, we show that (i) online channel of hybrid firm under blockaded entry may increase the social cost if the firms' delivery cost is sufficiently smaller than the consumer's transportation cost, and (ii) online competition under free entry may increase the social cost if the firms' delivery cost is sufficiently larger than the consumer's transportation cost. Finally, we discuss the strategic incentive of hybrid firms to reduce delivery cost and investigate the effect of the Internet maturity on the social cost.
